How Claude and Codex Are Changing Software Engineering
AI coding tools shift where engineering effort goes — towards specification, review, and verification.

From typing to directing
Tools such as Claude and OpenAI Codex can produce substantial code from clear intent. The engineer's leverage moves to framing problems, defining interfaces, and judging output.
Where leverage is real
Scaffolding, refactors, test generation, migrations, and well-specified features benefit most. Novel architecture, ambiguous requirements, and deep integration work benefit less.
Discipline still decides quality
Tests, review, CI gates, and clear standards are what turn fast generation into dependable software. Acceleration without verification just moves defects downstream.
